- Q:What is the car waterproof sticker material?
- C. metal technology and other: metal technology refers to the aluminum plate and other metal plate through the machine to suppress the concavity and convex surface, and then made of metal paint color, and finally after grinding, drawing and other production of the car stickers (car standard); Area can not be too large, can only be used for a small range of iconic car stickers.
- Q:How to do waterproof bathroom, construction process is what
- 2, brush the second time waterproof coating. It should be noted that the first coating to be dry before the second brushing, the specific time depending on the product characteristics may be. If the interval is too short, the first pass of the paint has not been dry, waterproof effect will be greatly reduced.
- Q:What material waterproofing can be mixed with cement sand
- Construction can also be used to produce waterproof pulp, waterproofing agent for the amount of cement 3 ‰ -4 ‰, the use of cement label not less than 32.5MPa.
- Q:Roof leakage, what materials do the best waterproof
- Therefore, rainy days should not be construction, to wait until the sun will dry the water before construction. The roof of a large area of leakage or a number of water leakage points, the first by the professionals to check whether the cracks, according to the previous program to deal with the cracks in the roof covered with waterproofing membrane, to enhance the waterproof effect, you can also shop On the insulation board, because the height of the insulation board in 20 cm or more, to achieve the protection of waterproof layer and thermal insulation of the double effect. Do not want to use the insulation board of the family, you can consider the use of steel mesh concrete, leak-proof effect is also very good. Wall cracks appear seepage, under normal circumstances the professional construction team will use the basket, by the maintenance staff in the external wall construction.
- Q:Cabinet is to buy finished products, or directly to the decoration company to do?
- Finished products to buy relatively easy to do some of the cabinet to do more solid material more assured because the plate is also a long-term environmental protection or woodworking directly do better feel that the company can quote their own under the woodworker comparison
- Q:Waterproof mortar expensive or dry mortar expensive
- Dry mortar is usually called hydraulic cement mixed mortar, refers to the dry sieve treatment of aggregate (such as quartz sand), inorganic cementing materials (such as cement) and additives (such as polymers) and so on a certain proportion of physical mixing Into a granular or powdered, in the form of bags or bulk transported to the site, add water, mix directly after the use of materials.
- Q:Find the construction steps for waterproof coatings
- 1, base surface treatment
(1) roof structure After the completion of concrete pouring, should be repeated water compaction, so that the surface of the grass-roots level, the flatness with 2m to check the ruler, ruler and grass-roots gap of not more than 5 mm, and only allow gentle changes.
(2) the base surface of the pores, rugged, honeycomb, gap, sand, etc., should be promptly treated, the base surface must be clean, no floating slurry, no water beads, no water; when the base surface appears more than 0.3 mm cracks , Should rush each 10 cm brushing 1 mm thick polyurethane coating waterproof layer, and then set the polyurethane cloth reinforcement layer, and finally brushing waterproof layer.
(3) all the corners are used 5 × 5㎝ 1: 2.5 cement mortar for chamfering, the angle made R = 10 mm rounded corners.

Construction acceptance: 1: grass-roots surface should be flat, no hollowing, from the sand, cracking and other defects. Base water content should meet the construction requirements of waterproof materials.
- Q:What is the difference between finished mortar and cement mortar?
- Finished mortar for dry areas, because the addition of lime, lime water retention is good; cement mortar for wet areas, because the high strength.
